21 Playing on lazer
The book's values are for stable unless a box says otherwise, because stable is what most of the sources played on. lazer is where the game is going, and several of its differences change training rather than just presentation.
| Difference | Why it matters for training |
|---|---|
| Unstable rate in real time | Since version 2023.1130.0 lazer measures UR in real time, so Double Time scores need no conversion. On stable you still divide a DT UR by 1.5 (Ch. 7) 51 |
| Difficulty adjustment built in | You can change AR, CS, OD, and speed without a third-party tool, which makes the isolation drills in Ch. 31 a menu option instead of a download 56 |
| Tablet area built in | Stable has no area settings of its own; lazer does (Ch. 16) 56 |
| Mod presets | Saved mod combinations, useful when a program calls for the same settings every session 56 |
| Slider judgement | Slider heads count toward accuracy, and tails are looser: on fast sliders you need only be tracking in the final 36 ms (Ch. 10) 55 |
| Input and frame rate | Input runs on its own thread at about 1,000 Hz, and the frame limiter caps there too, so frame rates beyond your monitor buy little (Ch. 18) 80,81 |
| Score multipliers | Mod multipliers differ from stable's, so don't compare scores across clients (Ch. 35) 62 |
| Daily challenge | A rotating daily map with its own ranking. Whatever it picks is variety you didn't choose, which is exactly what Ch. 23 recommends 61 |
lazer changes faster than this book does. Where it and the wiki disagree with a value here, believe them.
